This invention relates to improvements in machines for packaging material and is directed more particularly to improvements in machines for rolling up lengths of material such as paper 5 or the like.

The principal objects of the invention are directed to the provision of a machine for winding or rolling up lengths of material such as paper or the like into a fold or bolt.

According to special features of the invention the material is cut from a roll into lengths, then wound into a fold.

The machine is particularly adapted for paper such as crepe, paper which is sold in what are called folds. A fold is a length of paper rolled up in the form of a "relatively flat package or bolt which is inserted in a flat tube-like binder.

Paper such as referred to is sold at relatively low cost so that it is necessary in order to meet the requirements of low cost to package the paper at low cost. The machine of the invention embodies novel features of construction and arrangement to enable high speed operation and thereby facilitate the desired low cost production. It is characterized by many novel features of construction to facilitate efficiency in operation and has been found to be capable of mechanically performing the many operations heretofore performed by hand.

Referring now to the drawings in detail the invention will be fully described and to facilitate a clear understanding of the novel features of the machine and its operation reference will first be made to Fig. 16. 20

A length of material such as paper. is represented by L. This has been severed from a web in the form of a roll. The length is wound or rolled into what for convenience may be called a fold F which is relatively flat as shown and resembles a bolt of cloth. As will be explained, there are two winding mechanisms so that successive lengths are alternately fed to and wound up' by the said mechanisms. This facilitates speed in production.

It will be understood that the machine is adapted for operation on various materials wherefore the mention of paper is not to limit the scope of the invention to paper alone.

After the folds F are formed they are fed forwardly in the machine in the direction of the arrow 0. to a position indicated by A. Then the folds F are fed transversely in direction of arrow 12 to the position B wherein they are buckled, bent longitudinally or contracted for inserting into a] band or tube T.

The tubes T are in a flat condition in a stack and are fed forwardly from the stack in direction of arrow :1: to a receiving position C where they are opened up to receive the folds F. Successive buckled folds F are fed transversely in the direction of arrow c into successive opened up tubes T. Mechanism to be described opens the tubes and when the folds are inserted therein the opening up mechanism releases them and then the folds in the tubes comprise packages P which are fed downwardly in direction of arrow 1: to a stack from which the operator removes them.

A more detailed description of the machine will now follow.

Looking at the front side of the machine in Fig.

' 1 there is a rear end frame such as 2, a forward yond them as shown in Figs. 6 to 9 inclusive. It

will be understood that the frame parts may take any form desired.

The paper or other material is cut into lengths .at the rear end of the machine and is led to the forward end where it is rolled into folds. The folds are then fed transversely during which movement they are buckled and inserted in the tubes.

Roll supports I8 extend rearwardly from the frames 2 and 2 and are notched, as shown, to receive an arbor such as I2 of a roll. of paper such as R. Upper bars I4 carry a rod I 6 to which is attached a flexible strap I8, that bears on the roll R. A weight 28 on strap I8 tensions it so that it serves as a brake to prevent over-travel of the roll R. The web W of paper from the roll R passes over a lower roll 22 having a shaft 24 Journailed in the frames 2 and 2'. Another roll 28 above roll 22 co-operates therewith to feed the web W into the machine as will later appear.

The machine may be driven in any desired manner but for purposes of description a motor 26 for that purpose is shown on member 6, see Figs. 2 and 3.

A shaft 28 is journalled in brackets 29' fixed to frames 4 and 4' and carries a pulley 38 operably connected by a belt 32 to a pulley 34 of the motor 26. An upper shaft 36 journalled in frames 4 and 4' carries a pulley 38 which is connected by a belt 48 to a pulley of a shaft 42 journalled in frames 2 and 2. A pulley 29 on shaft 28 has a belt 3| thereon which engages pulley 38. A pulley 44 on shaft 42 carries a belt 46 which passes over a pulley 48 on shaft of roll 22. By means of the connections described lower feed roll 22 is rotated.

A rotatable knife carrier 58 (see Fig. 2) has a shaft 52 journalled in frames 2 and 2 and carries a knife 54 co-operating with a stationary knife 56 for severing the web W into lengths. The knife bar is rotated (see Fig. 3) from shaft 42 by means of a gear 68 on its shaft which intermeshes with a gear 62 on shaft 64 which in turn is operatively connected by gears 66 and to shaft 42. The knife mechanism operates in the well-known manner to cut or sever the web into successive lengths.

The upper roll 23 is mounted for movement relative to lower roll 22 by being journalled in levers 18 which are pivoted to frames 2 and 2' (see Figs. 1 to 3a). A latch 12 pivoted at 14 to a swinging lever H on the forward side of the machine has its lower end arranged to rest on a stop 16 as shown in Fig. 3a, whereby the roll 28 is held out of contact with the lower roll 22. By pressing outer end 18 of latch 12 the lower end of latch 12 is moved from off stop 16 so that the levers carrying the upper roll swing and allow the upper roll 23 to come to rest on lower roll 22 whereby they co-operate for feeding the paper. The roll 23 is automatically lowered by means of an arm 18 rigidly associated with arm 88 swingable on a pivot 82. A cam 84 having a nose 86 on shaft 64 is arranged by rotation of shaft 64 to swing arms 88 and 18 so that arm 18 strikes a pin 88 on part 12 to swing it from of! port 16.

The length of paper L is fed forwardly by means of a belt conveyor mechanism now to be described.

' Shafts 88, 82 and 84 are rotatable in frames 2 and 2' and carry rolls 88', 82' and 84. levers 88 on shaft 88 have rolls 86' in their outer ends. Rolls I88, I 82, I84 and I88 are journalled in the frames 4 and 4 as is a roll I88. Levers such as II8 adjacent each frame 4 and 4' are oscillatable on shaft H2 and carry rolls H4 and H6 in their lower ends. A plurality of relatively narrow endless belts III are carried by the rolls already described and pass over the roll II4 of levers III. These belts may be called the upper belts. Weighted idlers I28 swingable on shaft 88 function to tension the belts II8.

Rolls I28 and I22 in the frames 2 and 2 and rolls I24 and I26 on frames 4 and 4' support lower endless belts II8. Tension levers I26 operate on the lower belts.

As will be seen in Figs. 1 and '7. the belts are arranged so that their inner adjacent runs carry the lengths of paper so that they are discharged by the rolls H4 and II6 in the lower ends of levers H8. 1

As stated the levers II8 swing back and forth so as to position the rolls H4 and H6 alternately over separate winding mechanisms indicated generally by I88 in Fig. '1 and to be described.

The levers II8 are operated by a link I32 connected thereto, as shown, and to a lever I34 on a shaft I86. Cam members I38 on a shaft I48 engage rolls I42 of levers I46 whereby as shaft I48 rotates the members H8 are swung back and forth.

The winding mechanism will now be described with reference to Figs. 1, 4, 5, 6, 7, ll 12, 13, 14 and 15. There are two separate complete mechanisms which operate alternately for winding up the lengths of paper. Each winding mechanism consists of two groups of parts. The groups have similar parts and certain parts of one group co-operate with certain corresponding parts of the other group. One complete winding mechanism only will be described.

As in Fig. 6, outboard plates I58 are spaced from and secured to frames 4 and 4' by pairs of guide rods I52. A winder head I54 is slidable on each pair of rods I52. Each aligned pair of heads are for one winding mechanism. Upper rods I56 in outer plates I58 extend inwardly therefrom and have fixed to their inner ends spiders I58. These rods reciprocate slightly in plates I58 and may rotate therein.

Lower rotatable shafts I68 have keys I62. The heads I54 have sleeves I64 which are provided with slots receiving the keys whereby as the heads reciprocate they move relative to shafts I68. Also the heads slide relative to rods I56. Tubes I66 rotate in the upper part of the heads and carry plates I68 on their inner ends. Sleeves I18 in which tubes I66 rotate are fixed in the heads and these have fixed to their inner ends hubs I12. The members I64 are preferably faced with some material such as leather or the like as indicated by I 68.

Plates I14 are oscillatable on the plates I68 of sleeves I66. A pair of blocks I16 are slidable in the inner faces of plates I68. Hollow winding arbors or tubes I18 extend through the blocks I16 and through eccentrically disposed slots I88 in plate I68. They are threaded on their outer ends and carry nuts I82. The tubes I18 of one head co-operate with those of an opposite head.

As the heads reciprocate back and forth the tubes of the heads are carried.thereby from a winding position where their inner ends abut to a non-winding position where their ends are widely separated. W

In Fig. 6 the heads I54 of the winding-mechanism at the front of the machine are in winding position, while the heads I54 of the other winding mechanismare in non-winding position. In the winding position tubes I18 abut, as shown in Fig. 5.

To assure alignment of the tubes in winding engagement, a plug I98 of one tube is received in an opposite tube and the opposite tube carries a plug I92. The tubes I18 also carry perforations I94 in their walls. As has been explained, the. parts I66 are rotatable. They carry the plates I68 and I14 with which tubes I18 are associated so that the tubes are rotated. The length of paper is delivered to a winding mechanism when the tubes thereof are in engagement and in a horizontal plane.

As the plates I14 and I68 are rotated the rods rotate to wind up the paper to form a flat fold. To insure the paper being engaged by the tubes which are hollow the said tubes are connected to a suction means, later to be referred to, and the perforations function to permit the suction to draw the paper against tubes I18. After the length of paper has been wound, the heads are moved outwardly drawing the tubes from within and outwardly at the ends of the wound fold.

In order to vary the center to center distance of the tubes and to thereby vary the width of the fold the nuts I82 may be loosened and plate I14 rotated relative to plate I68. This'moves the tubes and blocks I16 in and out.

The blocks I16 have passageways I96 in communication with the hollow tubes I18. The plates I68 have passageways I98 in communication with an annular groove 288 of part I12 and to this passageway there is connected a conduit 282 extending to a suction means.

For rotating the parts for the winding operation there is a sprocket 2I8 rotatable on a sleeve 2I2 which is driven from a shaft 2I4 by a chain 2I6 engaging a sprocket 2I8 thereof. A detent 228 in sprocket 2I8 is pressed outwardly by a spring, as shown.

A driver 22! on a part 224 fixed to part I64 is engaged by a detent 228 so that part I64 is rotated by sprocket 2! when the head is in winding position as shown in Fig. 11. A gear I65 associated with part I64 is in mesh with a gear I61 fixed to part I66 whereby the part I66 is rotated to rotate the tubes.

A female clutch part 226 and sprocket 228 are rotatable on a sleeve 238 of outboard plates I58. These are continuously driven by chains 238' engaging sprockets 232 of shaft 2I4. When the heads I54 are moved outwardly from winding position towards plates I58 the parts 228 and 22I are disengaged so that the tubes I18 are no longer rotated.

It is desired that when the heads are in their non-winding and arrive at the winding position, the pairs of tubes I 18 of each winding mechanism be in a horizontal position and have their axes in the horizontal plane of their axes of rotation. This is accomplished as follows.

A lock 248 is slidable in the head I54, ithaving a disc part 242. A spring 243 acts on the lock and a rod 244 extending from the lock is arranged to abut a stud 246 when the head is in its inner or winding position. A notch or slot 248 in part 224 is adapted to receive lock 248. As the head approaches the winding position the rod 244 abuts stud 246 to pushgthe lock 248 inwardly releasing part 224 from. the head so it 5 may be rotated.

As the head moves outwardly to non-winding position the lock 248 is urged against part 224. When in full outward non-winding position a male clutch part I69 associated with gear I65 10 enters rotating female clutch 226. Through the clutch parts I64 and 224 are rotated until notch 248 registers with and receives lock 248, whereupon part 224 is locked in certain position holding the upper rotating parts against rotation 15 with the winding tubes in the desired position. The clutch parts are adapted to slip to permit, of rotation of part 226 relative to part I65 while the head is in non-winding position a spring 23I allowing suflicient movement of the clutch 226 go to allow of slippage of the said clutch parts.

To jog the paper while it is being wound up the rods I56 are reciprocated slightly to reciprocate members I58 which strikes the edges of the paper on the tubes I18. This is accomplished by 25 a cam 248' on shaft I68 having a projection 242' which engages the lower end of a lever 244'. The lever is pivoted at 246 and its upper end rides in a groove 248 of a collar 258. As lever 244 is. swung back and forth by the cam 248, rod I56 is reciprocated or vibrated so that member I58 vibrates or jogs the paper.

The heads I54 are reciprocated by levers 266 mounted on pivots 254 for swinging movements and have their upper ends connected by links 256 36 to said heads (see Fig. 4). A central shaft 269 carries arms such as 268 having pins 262 in their outer ends. Connectors 264 have slots at opposite ends, as shown. The slots at inner ends of the connectors receive pins 262 and the slots 40 at their outer ends receive pins 266 of levers 266. There are two shafts, 218 and 212, which are geared together by gears 214. One, such as shaft 218, has an arm 216 carrying a roll 218 which as i it rotates clockwise strikes the upper side of a rocker 288 associated with levers 268, to rotate said levers which through connectors actuate levers 266.

Rocker 288 is in winding position in Fig. 4 but is about to be moved to move the heads out- 5 wardly to non-winding position. As arm 216 I comes to operating position on rocker 288 cam 298 on shaft 212 passes ofi the right hand end of rocker 288, allowing the rocker to swing counterclockwise so that levers 268 operate the connectors.

The mechanism just described is for operating the heads of one winding mechanism but there is a duplicate set of parts for operating the heads of the other winding mechanism which are associated with shafts 269, 218 and 212.

One shaft 218 has a bevel gear 292 fixed thereto which is in mesh with a gear 294 on a vertical shaft 296 and said shaft is at its upper end geared by gears 298 and 388 to shaft I48 (see Figs. 6 and 7).

As will be observed, the pairs of rods rotate to wind or roll the paper into folds after which by outward movements of the heads the folds are released. They are received on elevators when released and deposited on a conveyor mechanism which moves the folds in the direction of the arrow a in Fig. 16. This is accomplished as Y shown in Fig. 7.

Endless spaced conveyors 3I8 are supported on carriers 3l2 of shaft I40, M4, M6, 3I8 and 320, they carry spaced pushers 3H and travel in the direction of arrow a.

Arms 324 and 326 rock on shafts 328 and 330. Other arms 332 and 334 rock on shafts 336 and 3 l4. A lever 338 is pivoted to arms 324 and 332 and another lever 340 is pivoted to arms 326 and 334 and fold supports 340 and 342 on levers 338 and 340 are rigid therewith. The arms and levers are so arranged that as they oscillate the supports 340 and 342 move up and down and are maintained in substantially horizontal planes. One support 340 is in upper position for receiving the fold to be released by the winding mechanism at the left after which the arms are operated to lower support 340 so the fold thereon is deposited on the conveyors. Then a support is provided for each winding mechanism and they are alternately operated.

Cams 350 and 354 on shaft I in the rotation of said shaft engage the end of levers 352 and 356. The lever 356 is rigidly associated with arm 324. The arm 352 is connected by link 358 to arm 326. By means of the mechanism described the supports 340 and 342 are operated alternately.

As the folds are deposited on the conveyor or conveyors 3l0, the upstanding pushers 3| I thereof engage the said folds and advance them to the position A in Fig. '7 wherein they pass onto bars 360 carried by a pair of levers 362 and 364. There are preferably two pair of levers for two bars 360. The levers are mounted for rocking movements on shafts 366 and 368. A cam 310 on a rotatable shaft 312 operates on a roll 314 of a lever 316 which is slidable on shaft 312. The said lever 316 is connected to an arm 318 fixed on shaft 368 whereby the cam. as it rotates causes the levers 362 and 364 to swing back and forth whereby the bars may receive the folds from conveyor 3l0 and carry them to the right against upwardly extending stops 380. As the bars 360 move to the right the folds are removed therefrom by the stops so as to drop into a table 382 in which a conveyor in the form of a chain has its upper run traveling in the direction of arrow b. This chain carries projections as is usual for engaging the rear ends of the folds.

The table 382 to the right of position A as in Fig. 6 has a narrow portion 386 which is provided with side walls 388. A bracket 390 has rear arm 392 pivoted to brackets 334 and its forward end is forked as at 395 and in this fork a wheel 396 is journalled. As the folds are moved along table 386 they pass under wheel 396 which by movements up and down of bracket 390 bears on the folds. the folds, by means of a belt 400 in engagement with a. pulley 402 on the shaft of wheel 336 and a pulley 404 driven by belt 406 from shaft 212.

The wheel 396 is located at what may be called the buckling position (see Fig. 16) wherein the folds are buckled. This operation is accomplished as follows (see Figs. 6 and 8).

Side plates 4I0 are pivoted at 2 to table 386 to swing between horizontal and elevated positions. As folds are conveyed to the buckling position the plates are moved to elevated position the wheel 396 being on the folds. As side plates 0 are elevated they move the longitudinal sides of the folds upwardly forming more or less of a U as shown in dotted lines in Fig. 8. An arm 4I4 pivoted for rocking movements carries a stud H6 in its outer end and connectors 4|6 pivotally connected at their upper ends to the plates 4| 0 have lower slotted ends receiving stud 4i 6.

The wheel 396 is rotated, so that it moves' A cam 420 on shaft 312 acts on a. roll 4i! of lever 4 whereby the connectors are operated to actuate the plates.

After the folds are buckled they are fed forwardly and inserted in a wrapper of tubular form. The tubes are in flat form in a stack and are fed successively to fold receiving position wherein they are opened up. After a fold is inserted in a tube the completed package is moved to a stack thereof. It will be understood that as a fold is fed onto the buckling mechanism it moves a previously buckled fold along.

At the right hand end of the machine, as shown in Fig. 6, there is a tube magazine formed by vertical side walls 420'. This magazine is for a stack of wrappers or tubes T in flat condition such as shown in Fig. 16. A table or slide 422 is reciprocable in guides such as 423 in frames 3 and 3' and transversely of the direction of travel of the folds. The stack of superposed tubes in the magazine rests on the table 422. Suction openings 424 are provided in the table 422 which when it is in its rear position underlie the stack of flat tubes. As the slide 422 moves forwardly or to the right, the suction action causes the lowermost tube to be carried by the slides from beneath the stack to fold receiving position at the right of a plurality of trips 425. As the slide 422 moves to the left the edge of the fold brings up against the trips. As the slide reaches its leftmost position the fold is dropped onto the low part of the slide and the higher part of the slide is in position to take on another fold. When a fold is on the lower part of the slide it is in receiving position and is opened up and held in open relation while a buckled fold is inserted therein. The plates 0 which buckle the folds are held in buckling relation while the folds are advanced therefrom into the opened up tubes.

A carriage 430 is slidable up and down in brackets such as 434. The carriage is of some length to overlie the tubes on the slide in receiving position. The slide carries a series of spaced suction nozzles 436. The slide 422 has a plurality of suction openings 42i which underlie the fold thereon. With a tube in flat condition on table 422 and with the nozzles and openings connected to suction means the member 430 descends so the nozzles bear on the tube and then as it elevates the fiat carton is acted upon by suction so that it is opened up as at C in Fig. 16. The fold is then fed forwardly into the tube and the suction means releases the tube so it assumes a fiat condition on the flat fold.

A lever 440 fixed to a shaft 440 journalled in a bracket 442 has its forward end connected to member 430. As the lever swings the member 430 and nozzles are moved up and down. A link 444 connected to lever 440 is connected to a lower swinging lever 446 which is actuated by a cam 448 operating on a roll 448 thereof, the earn 448 being fixed to shaft 312.

After a fold is inserted in a tube to complete the package, the package is moved to the right (see Fig. 9) to the bottom of a stack of finished packages and in the direction of arrow 11 shown in Fig. 16.

This is accomplished by transporters such as 450 on the upper ends of bars 452. Arms 454 rocking on shafts 456 and 458 have their outer ends connected to bar 452. A lever 460 swinging on shaft 458 has a roll in contact with a cam 462 on shaft 312 and its upper end is connected by link 464 to a lever 466 rigid with upper lever 454. As lever 460 is swung back and forth by its cam the levers 454 swing up and down so the transporters pass through a more or less elliptical path underneath the package on slide 442 and elevating it. The slide 422 as it reaches the position at the extreme right moves the package over transporter 450.

A lever 410 swingable on pivot 412 carries a bar 414 on its upper end and from this there extend a plurality of supporting rods 416. This lever swings back and forth from the position shown in Fig. 10 to a position at the right thereof to carry the rods beneath a table 416.

The stack is supported by the rods 416 and by the transporters. That is, as the transporters elevate a package the rods 416 move to the right from beneath the stack so the package on the transporters support the stack. Then the rods move to the left beneath the package on the transporters and support the stack until it is again supported by the transporters. Thus the slide moves a completed package to the right and over the transporters which elevate the package so it becomes the bottom one of a stack A cam 418 on shaft 312 engages a roll of a lever 480 rocking on shaft 458 and this is connected by a link 482 to lever 410. A link 484 is connected to slide 422 and a lever 486 while a link 488 connects lever 486 to a lever 490 rocking on shaft 458'. This latter lever is operated by a cam 492 on shaft 312.

The nozzles 436 are connected by conduits 431 to a header 439 and said header is connected to a pipe I. A conduit 4|43 connects opening 424 to pipe I while a header 443' is connected by several conduits 445 to the several openings 42l in the slide while a conduit extends from header 443' to pipe 44!.

The pipe 4 is connected to a suction device such as 500 at the rear end of the machine. This is driven from the motor 26 by means of the belt and pulley drive consisting of pulleys 502, 504, and belt 506. A valve mechanism V in pipe I has a, part operable by shaft 312 whereby the different units are in timed relation connected to the course of suction. Thus the openings are under the influence of suction for the various operations. 7

A pulley 5l0 of shaft 28 carries a belt 512 which engages a pulley 5l4. A gear 5I6 associated with pulley 5l4 meshes with a gear 5l8 which rotates with another gear 520. The latter gear 520 meshes with a gear 522 and this rotates with a gear 524 in mesh with a gear 526 on shaft I40 whereby said shaft is driven (see Fig. 1).

A pulley 528 associated with gears 522 and 524 carries a belt 530 which engages a pulley 532. A pulley 536 has a belt 534 therearound engaging a pulley 538 of shaft 312 whereby this shaft is driven for operating the buckling and feeding mechanism last described.

A frame against which the completed folds may rest is shown in Fig. 10. It consists of a bar 540 extending between brackets 434, links 542 pivoted at opposite ends to said bar and to vertical members 544, a link 545 pivoted at opposite ends to members. The pivots are arranged so that the members may be moved, from the full line position and the position shown in dotted lines and positions therebetween and will hold the members in said positions.

While I have described the invention in great detail and with respect to a preferred form thereof, it is not desired to be limited thereto since many changes and modifications may be made therein without departing from the spirit and scope of the invention.
